CHANNEL-GEMENTING MACHINE.

Specification of Letters Patent. Patented Sept. 26, 1911 Applicationfiled July 15, 1904. Serial No. 216,660.

To all whom it may concern:

Be it known that I, CHARLES P. STAN- BoN, a citizen of the UnitedStates, residing at Lynn, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inChannel-Cementing Machines; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The present invention relates to channel cementing machines which areadapted to apply cement to the channel and channel flap of the outsoleof a boot or shoe.

The object of the invention is to provide an improved means for guidingthe shoe to the brush of a channel cementing machine in order to adaptthe machine for operation upon soles provided with a narrow channel flapsuch as the soles of welted boots or shoes and soles provided with whatare known in the art as English channels.

The invention is intended primarily as an improvement on the channelcementing machines disclosed in applicants prior applications, No.195,598 filed Feb. 27, 1904:, and No. 213,781 filed June 23, 1904, toadapt said machines for operation upon the soles of welted boots orshoes or upon soles provided with English channels, but it is to beunderstood that the invention is not limited to use on the channelcementing machines disclosed in said applications, but is equallyapplicable to other forms of channel cementing machines.

A channel cementing machine embodying the present invention comprises acement applying brush and guide arranged to enter the channel and guidethe shoe to the brush. In accordance with one feature of the inventionthe guide is separate from the brush which moves independent-1y thereof.

It has heretofore been proposed to provide a cement applying brush witha central rib formed integral with or rigidly secured to the hub of thebrush and arranged to enter the channel and act as a guide for the shoe.The rib engages the channel for a suflicient portion of its length tointerfere with the guiding of the shoe while the toe portion of the shoeis being operated upon,

and on account of its rotating movement tends to ride over the channelfia-p or over the outer edge of the sole. By providing a guide separatefrom the brush the guide can be arranged to remain in the channelwithoutany tendency to leave the same and need extend only acomparatively short distance longitudinally of the channel so that themanipulation of the shoe is not interfered with and the shoe can beproperly guided while all portions of the channel are being acted upon.

In accordance with another feature of the invention, the channel guideis yieldingly mounted so as to be movable in a direction substantiallyperpendicular to the surface of the sole. The guide can thus be soarranged thatit normally projects a considerable distance beyond theperiphery of the brush, in position to readily engage the channel of ashoe presented to the brush, and is caused to remain securely seated inthe bottom of the channel as the shoe is fed along beneath the brush.This feature of the invention is not limited to a construction in whichthe guide is separate from the brush although such a construction ispreferred for the reasons above stated.

Another feature of the invention contemplates vibrating the channelguide longitudinally of the channel as when such a vibrating movement isimparted to the guide less resistance is offered to the feeding of theshoe and any wrinkles or puckers in the channel flap are moreeffectually straightened out and the cement is more thoroughly appliedto all portions of the flap.

In addition to the features of invention above referred to, the presentinvention also consists in certain devices,combinations and arrangementsof parts hereinafter described and claimed, the advantages of which willbe obvious to those skilled in the art.

The various features of the present invention will be clearly understoodfrom an inspection of the accompanying drawings in which- Figure 1 is aview in side elevation of a portion of a channel cementing machine withthe preferred embodiment of the present invention applied thereto. Fig.2 is a view in front elevation of the parts illustrated in Fig. 1, andFig. 3 is a detail sec tional view of the cement applying brush, the camfrom which the channel guide is vibrated, and the end of the shaft upon.which the cam and brush are mounted.

Referring to the drawings 1 indicates the head or frame of the machineupon the upper front portion of which is rigidly mounted a frame 2. Theframes 1 and 2 are provided with suitable passage ways for the cementwhich lead to a delivery tube 3 from which cement is supplied to thebrush. The passage way to the tube 3 is controlled by a suitable-valveat the lower end of a rod 4 mounted to reciprocate in Vertical guidewaysin the frame 2. This rod is held depressed by means of a spring 5 coiledaround the rod and bearing against a block 6 secured to the rod and maybe raised by means of a lever 7 pivoted upon the frame 1, the forwardend of which extends beneath the block 6 and the rear end of which iscon nected by a rod 8 to a foot treadle. An actuation of the lever 7 bydepressing the foot treadle raises the rod 4: and the valve connectedtherewith so that the flow of cement to the brush can be controlled bythe operator and the cement delivered at such times and in suchquantities as may be desired.

The cement applying brush is secured upon the forward end of a rotatingshaft 9 mounted in bearings in the lower portion of the frame 1, andconsists of a cylindrical hub 10 and a series of radial tufts ofbristles 11. The tufts of bristles are set in holes bored radially inthe hub of the brush and are secured therein by thin blocks or wedges 12which are fastened to the hub by means of securing pins 13. The blocks12 separate the bristles as illustrated in Fig. 3 so as to form apassage way to receive the channel guide hereinafter described. The hub10 of the brush is secured upon the end of the shaft 9 by means of ascrew 14: and is provided with a pin 15 which enters a groove in theshaft 9 so that the brush is caused to rotate with the shaft. v

The channel guide is indicated at 16 and is formed upon the lower end ofa rod 17 mounted to move vertically in bearings formed in a frame 18.The rod 17 is located at one side of the brush and its lower end iscurved substantially concentric with the brush so that the guide 16 isarranged directly beneath the brush and will enter the passage way inthe bristles of the brush formed by the blocks 12 when the guide israised. It will be noticed that the guide 16 depends pivotlike beneaththe brush and at a point substantially central of the field of actionthereof, permitting free adjustment of the work in any direction at saidcentral point about said guide. The rod 17 and the guide 16 carriedthereby are normally held brush.

depressed by means of a spring 19 coiled around the rod and interposedbetween the upper bearing on the frame 18 and a block 20 secured totherod, the block by contacting with the lower bearing in the frame 18limiting the downward movement of the rod. When the rod is in its lowestposi tion the guide 16 extends below the periphery of the brush in aposition to enter the channel when a shoe is presented to the The guideseats itself in the channel before the shoe is brought into contact withthe brush so that a correct positioning of the shoes is insured beforeany cement is applied thereto. As the shoe is pressed against the brushthe spring 19 yields and the guide 16 is raised as high as desired oruntil a collar 21 adjustably secured to the rod 17 contacts with thelower bearing of the frame 18. By adjusting the collar 21 on the rod 17the extent of the upward movement permitted to the channel guide can bevaried so that by these means the pressure of the shoe against the brushcan be adjusted and the amount of cement applied to the shoe regulated.In order to prevent the rod 17 from turning in its bearing the block 20is extended rearwardly as illustrated in Fig. 1, and is provided with aslot which engages a vertical pin 22 projecting upwardly from the frame18.

It is desirable that the channel guide 16 be vibrated during theoperation of the machine longitudinally of the channel and to this endthe frame 18 is pivotally mounted upon a stud 23, and is provided withan arm in which is journaled a roll arranged to engage the periphery ofa cam 24 secured upon the forward end of the shaft 9 at the rear of thecement applying brush. The roll is held in engagement wit-h the cam bymeans of a spring pressed plunger 25 which bears, against the frame 18and which is mounted in a bracket 26 secured to the frame 1. The stud 23upon which the frame 18 is mounted is arranged parallel with the axis ofthe cement applying brush and thus the vibrating movements imparted tothe frame 18 by the cam 24 and the plunger 25 cause the guide 16 to bevibrated in the direction of the feed and longitudinally of the channel.The stud 23 is secured in the bracket 26 and in order that the guide 16may be brought into a position in line with the center of the brush. thebracket is adjustably secured to the frame 1 by means of a bolt passingthrough a slot in the bracket as is clearly indicated by the dottedlines in Fig. 1.
